Instantaneous capacitor current.....

[archie18]

Hello Everbody,
I have one doubt about capacitor discharge current.
I am charge a 0.47uF capacitor through 5.6K resistor. Vcc is 5Vdc
After some time say 1 min I directly short the capacitor without any resistor ...what would be the instantaneous discharge current ?
Thx,

It deppends of the Equivalent series Resistor (ESR) of the capacitor that usually is small. SO the current is V/ESR = I
It is a very bad practice to do that because the life of the capacitor decreases, thr robability of failure increases. If it is an electrolitic capacitor it could be damage in only one try.A good practice is using a resistor that takes several seconds to discharge.
